Musk may be joking, but seeing as how he wants to colonize Mars and taking into account his simulation ideas, discussing a metal suit with the government seems plausible.

A Department of Defense spokesman says Musk met with Secretary of Defense Ash Carter on Wednesday in regards to “innovation,” a word that can mean a whole lot of things when you’re talking about a billionaire and the US government.

At the end of the day, Musk may simply be trying to win over more business for SpaceX, but I like to think we’ll have a real-life Iron Man on our hands in the near future.
